Answer: Prophase
Explanation: Prophase, is the first and longest phase of mitosis. First, chromtain condense it into chromosomes and the nuclear membrane breaks it down.
Explanation:
A frameshift mutation is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes.
